Title: Time-wavelength multiple access optical communication systems and methods
Inventor: SWEETSER JOHN
IPC: H04B10/12
Filed: 1999-08-10
Granted: 2005-04-12
Abstract: Methods and apparatus for optical communication are disclosed. An optical data stream (220) is encoded (201) to produce an optical data stream having a predetermined time-wavelength spectrum. Two or more encoded (201) data streams are combined in a transmission medium (e.g., optical fiber) and the combined data stream is decoded with decoders corresponding to the encoding of the data streams, producing decoded outputs. The decoded outputs include a portion corresponding to a selected data stream as well as a portion corresponding to unselected data streams (crosstalk). A nonlinear detector receives the decoded outputs and rejects crosstalk. Coders produce temporal delays and phase shifts specified by a time-wavelength code for the spectral components of an input optical signal. Some coders convert optical signals encoded with a first time-wavelength code into an output corresponding to a second time-wavelength code. Temporal delays and phase shifts can be selected to compensate for dispersion in a transmission medium. Coherent coders are, provided in which the phase shifts produced on the spectral components of an optical signal are controlled within about one half of the wavelength of the spectral component.

Title: Method and system for determining weld bead quality
Inventor: LUDEWIG HOWARD W
IPC: B23K31/12
Filed: 1999-11-16
Granted: 2008-04-29
Abstract: A method for determining the quality of a weld bead includes producing a weld bead along a work surface during a welding process and scanning the weld bead with a scanner to obtain positional data points for defining a weld bead profile. The weld bead has a weld toe zone or region, which is formed at the interface between the weld bead and the work surface.  A curve fit is determined for the weld bead profile based on the positional data points obtained by the scanner. The toe radius is derived based on the curve fit and is then compared to a first predetermined limit and a second predetermined limit, greater than the first predetermined limit, to determine the quality of the weld bead. If the weld toe radius is less than the first predetermined limit or greater than the second predetermined limit, the welding process is modified to produce a weld bead with a toe radius that falls within the desired range. In one embodiment the weld toe radius is determined from first and second derivations of a numerical relationship representative of the curve fit. In another embodiment the curve fit is compared to a plurality of curves to find a corresponding match and the weld toe radius is determined from the matching curve.

Abstract: A dielectrically-loaded antenna for operation at frequencies in excess of 200 MHz includes an antenna element structure disposed on a high dielectric constant core, which element structure comprises a pair of laterally opposed groups of helical antenna elements. Each group comprises first and second mutually adjacent elements, of different widths providing looped conductive paths on the antenna, formed by the first elements of each group and the second elements of each group respectively, which resonate at differing respective resonant frequencies to yield a relatively wide operating bandwidth.  The helical elements of each group define, between them, part of an elongate channel which has an overall electrical length in the region of n.lambda./2 within the operating frequency band to provide isolation between the looped conductive paths. The major part of each such channel is located between the elements so as to minimise intrusion into other conducting parts of the antenna.

Title: Hitless protection switching
Inventor: COURTNEY JOHN
IPC: H04L69/40
Filed: 2002-05-22
Granted: 2010-04-27
Abstract: The invention provides a method and apparatus for providing hitless protection switching in a transmission systems which support a standardised implementation of virtual concatenation. A switching apparatus is arranged to receive data signals on at least two transmission paths and to output data from a selected one of said transmission paths. The apparatus is arranged to align the respective received data signals so that a selector mechanism can select between corresponding elements of the received data signals. This arrangement allows hitless switching to be performed since there is no loss or repetition of signal elements when switching occurs. In a preferred embodiment, data in respect of each frame of each data signal is stored and the selector mechanism selects between paths on a frame-by-frame basis by comparing quality information carried by the data signals. This arrangement offers a very low end to end Bit Error Rate (BER) performance. The invention is suitable for both synchronous and non-synchronous networks (for example, OTN)which implement standardised virtual concatenation.
